NOISEIESS RAILROAD-CROSSING.

Specification of Letters Patent.

Application filed October 12, 1910. Serial No. 586,625.

Be it known that l', Grenen GUILBAULT, a citizenl of the United Statesr` and a resident of New Orleans, in the parish oi Orleans and 'State of Louisiana. have invented a new and 'useful Noiseless Railroad-CroSs ing, of which the followingv is a full, clear, and exact des'eription.

The eloject' and purpose et the invention is to provide a railroad crossing'. in which the vibration and noise due to passing trains Shall he eliiniinlted. and the destruction of the rparts due to the poundingI or' the wheele shall be materially lessened; thereby providing a crossing' which Shall cause little annoyance to the neighborhood and in which the parte need not he frequently replaced.

there 'two railroad tracks cross each other. it is necessary to channel the upper hearing portions of the rails in order to permit the ear `wheel 'flanges to pass over. AS the succession of wheels pass over the rails considerable noise is caused and there is a series of Shocks or blows on all the parte4 which loosens the connections. My invcntion overcomes these objections hy-providing each rail adjacent the point oic intersec- Ition with a pivoted lever, there heing a pair of interaeeting leverS at the interseetioi'i ot two rails. A hell-crank lever is pivoted to each tiret-mentioned lever and is in operative relation with a. Sliding hloelv' which is adapted to he brought into engagement' with the ether intersecting lever wherehy the ear wheels pass o er the top of this lever and do not engage the ehannelS in the rails.

ln the accompanyincl sheete ot drawinee, which forni part et this specification, and. wherein in set forth the preterrei'l t'orin et my invention, Figure 1 ie a plan view ot' a. railroad crossing provided with my invention; Fig. 2 is a side view'ot one rail equipped with the. pivoted lever7 the parte being` Shown in the position just. helore. a. car wheel passes over; Fig'. ie a side view of the rail (which intersects with that one set torth in Fig. il) provided with the pivoted lever. the parte being shown in the position when a ear wheel ia passing; Fig, l in a Ieet-tional view on the line fl ft ot' Fir. i loolvinpr in the direction of the arrow; and Fifi. 5 is a. Sectional view on the line 5- 3 loolv'ing in the direction oi' the arrow.

passes the portion H of the lever B (shown A in Fig. and directly thcreahove it. is provided on its upper surface with the channel K to accommodate the tiantrc of a car wheel travelingat right angles to the rail 1. The tree end oi this lever is provided with an extending` portion L having ay tapered snrtace M; on the opposite Side oi the channel K also the top Surface is tapered, as at M. The base portion of therail is provided with a suitable leaf Spring- O or any other appliance hearing againat the tree end of the lever in order to maintain its Central upper surface 'lush with the upper surface ot"the rail.

trllhe lever A provided at about its eentral portion, with a` bell-crank Cjpivoted thereto at, e hy means of a pin and having at its opposite end a slot m in engagementI with a pin f/ carried hy a Sliding` block d; the hloeltr (Z hears on thc `bottom flange ot the rail, is movable therealong and in operative position rests on the plate /t carried hy the intersecting rail 3, and under ythe lever ll therehy preventing this lever from i'noving` downwardly about', itspivot e.

k'lhe lever l, shown in Fig'. 3, is Substantially Similar to lever A, being` provided ywith a recess ll wherehy the lever A may passthrough: it is also provided with the hell-eranlzfrf in el'ig'ageinent with the I@lidingr nloek d 'which is adapted to he Inoved under the lever A (as shown in Fig. 3i therehy preventingthis lever 'from turning as shown in Fig. il.

Arrshown.particularly in Figs. 4 each o'tE these levers A and l is held in po sition .against thel respective rails hy nlians ot' a protecting;` easingv For G. llaeh of these easing's is provided with av pin f and f extent-ling" transversely thcireo'lE and'intlo the slot r and r in each of the helhciranics. the

plane of the slot- /r in each bell-crank loe-` face of the rail;as a car wheel (denoted X in Fig. 2) approaches the crossing from the left the f iange thereof comes into contact with the tapered portion M of tl'ie lever A and the lever turns downwardly about its pivot a; in moving down the lower end .of the bell-crank c, carried thereby will swing to the right and in doing so will movi,` the .sliding block d to the right until it comes to rest on the plate /iunder and in contact with the intersecting lever B. 'l`liis movement of the block (Z to the ri( ht results because of the fixed pin f carried ily the rasing F; the parts are so proportioned that the block is in its linal position on the plate h when the surface of the wheel is about to cross over tlie intersecting rail 3. \Vlieii the block is in this position the intersecting lever B Cannot swing downwardly on its pivot because the block is directly under this lever and will prevent siicli movement; this lever is, therefore, held flush with theintersecting rail 3 and the channel in tliisyrail is closed; the car wheel will pass overzgivithoiit noise or shock. It is immaterial what the diameter .of the car wheel or -the ,depth of the flange may be in the operation of the device. ,v/

In' Fi 3 I have shown the position of the parts W en a car wheel is passingEover the crossing in a direction at right a'tigles to the rail shown in Fig. 2 which has just been described. The operation of thc parts in this figure is substantially the saine and the car Wheel is shown in the act ot passing over the intersecting rails. The sliding block is in its final position on the plate and the lever A is held against downward movement. After the car wheel (or train) has passed, the lever A or B v(depending on which rail the train has passed over) will return to its` normal upper position because of the spring O or O or any other appliance bearing against its free end. ln coining back to the normal position the sliding block al or d will move along the base of the rail into the position shown in Fig. 2 when the crossing is in position to be again operated by a train passing over either track.

It is obvious from Fig. i1. that -each crossing of single tracks will have tour pairs of intersecting levers. 'llie crossing may be atta right angle or may be at any angle, asiar as the operation ot my device is concerned it being applicable to crossings ot any number ot' `trac-lcs and atv any angle to each other. j

Havin thus described my invention` what I c aim as new and desire to secure by Letters Patent is:

1. In a noiseless railroad crossing, two intersecting rails, a pivoted lever carried by each rail and means carried by eaeli lever adapted for engagement wit-h the other when the said lever is moved by a wheel passingr over one rail, whereby the lever carried by'the other rail is locked in position thereby closing the channel 1n the rail over which the wheel 1s passing. t'

2. In a iioiseless railroad crossing, a plurality ot' intersecting rails, a movable lever carried by each rail adjacent the point of intersection, slidalile means connected to each lever and adapted to come iiito engagement'. with the other lever when -a wheel comes into engagement with either lever whereby the l'hannel in the rail over which the wheel is passing is closed.

3. ln a iioiseless railroad crossing. .i plurality ot' intersecting rails, pivoted levers carried by each of the rails. the levers intersecting each other, and sliding means cai'-l riedby each lever and adapted-to cpiiie iiito contact with the other lever andpreveiit. movement thereof when engaged by a Car wheel thereby closing the cliaiiiiiel in the rail over which the wheel is passing.. i

4. ln a noiseless railroad crossing` two intersecting rails, members carried by each rail adjacent the point ot' intersection. the Said members being niovalily mounted thereon, means carried by each rail and operable by the movement of each ii'ieiiiber and movable into engagement with the other member when the tirst member is iii engagement with a car wheel, whereby the second niember is prevented t'roiii moving.

5. In a noiseless railroad crossing, two intersectingrails, movable members carried by each of the rails and also in intersecting relation, the upper surfaces of said movable members being normally flush with the upper surfaces of the rails, movable blocks carried on the base portion of each rail and means connecting cach movable member with one of the blocks whereby either of the movable blocks may be brought. into engagement with one of the movable members by a car wheel, whereby movement of that member is prevented and the channel iii the rail over which theY carwlieel passes is closed.

6. A noiselcss railroad crossing comprising intersecting rails, levers carried by each o't` the rails at the point of intersection, the said levers normally closing the channel in each rail at the point of intersection, and

'means carried by each rail aiid cooperating means connecting each ot the said means :iiid- `:ich lever operable by a` passing cai'- wheeh whereby one ot the levers may be hield ii'i normal position thereby closing the channel in the rail over which the c'ar wheel is passine. y

7. A noiseless railroad crossing comprising intersecting rails, movable members carried by each of the rails adjacent the point `ot intersection, and means whereby the members may be heldin position thereby closing the channels in the intersecting rails, means carried by each of the rails and a cooperating means between each of the said means and each movable member and operable by a passing car wheel whereby the other movable member is held in position to close the channel in which it lies.`

8. A noiseless railroad crossing comprising intersecting rails, a pivoted lever carried by each rail adjacent the point of int-ersection, the pivoted lever being flush with t-he rails whereby the channel in each of the ails is closed7 a sliding block carried by each rail and means of connection between each sliding block and each pivoted lever, whereby when a car wheel comes into engagement with one ot' the levers the block will be moved into engagement with the other lever thereby holding` the other lever in position whereby the channel in the rail is closed.

A noiseless railroad crossing comprising` intersecting rails, a pivoted lever carried by each rail adjacent the point ot inter-j section7 means engaging each of the levers whereby the upper surfaces thereof are held flush with the surfaces ot the rails, a casiilg adjacent each of the ails, the pivoted lever being` held bei ween the cas-ings and the rails thereby closing the channels in the rails,

means 'carried by each lever and adapted to be moved into engagement with theother lever by a passing car wheel whereby the other leveris held in position thereby closing the channel in the rail over which the wheel is passing. i

l0. A noiseless railroad crossing compris ing intersecting rails, a movable member carried by each rail adjacent the point of intersection, a casing adjacent each rail inclosing the movable members and means earried by each movable member and coperating with sliding blocks adapted to be brought into engagement with the other movable member by a passing car wheel, pins on each casing cooperating with each of these means whereby the other movable member is held in position thereby closing the channel in the 'rail over which the car wheel is passing.

11. A noiseless, railroad crossing comprising intersecting rails, and pivoted levers carried thercby and normally closing the channels in the intersecting Tails, and a sliding means in cooperative relation with each lever operable by a passing car wheel whereby the channel in .the rail at an angle to the rail over which the ear wheel is passing may be held closed while the car Wheel is passing thereover.
